华中五味子的营养成分与核型研究

Analysis on Nutrients and Karyotype of Schisandra sphenanthera Rehd. & Wils

华中五味子果实营养物质含量丰富，尤其是蛋白质、氨基酸、维生素和矿质元素的含量明显高于苹果和柑桔，是值得开发和利用的野果。核型分析表明：华中五味子的核型为原始的“１Ａ”类型，染色体数目为２ｎ＝２８条，核型公式为２ｎ＝２Ｘ＝２８＝２６ｍ＋２ｓｍ。在植物的系统进化过程中。

The fruits of S.sphenanthera Rehd are rich in nutrients. In particularly, Protein, amino acid, vitamin and mineral elements are richer than that of apple and orange. Which is the wild fruits worthy of developing and using. Karyotype analysis showed that the kargotype of S. spenanthera Rehd is more original 1A genotype, the number of chromosome is 28, karyotype formula is 2n=2X=28=26m+2sm. During plants systematic evolution, S.sphenanthera Rehd is more original.
